Description

Technical Field

[0001] The present disclosure relates to the field of cabin integration, and more particularly to overhead bins (especially piezoelectric embedded overhead bins), a luggage storage system including such overhead bins, and a method for notifying the space occupancy of overhead bins. Background Art

[0002] Generally speaking, according to the current overhead bin technology (e.g., overhead bins on aircraft), it mainly focuses on two directions: one is the design of pull-down overhead bins and their auxiliary mechanisms; the other is the detection technology of the volume and weight information of overhead bins, including cameras, infrared, weight sensors, etc. However, the existing technologies cannot provide passengers with a good boarding experience. For example, passengers need to spend time looking for a suitable overhead bin to store their luggage, which prolongs the boarding time.

[0003] The present disclosure has been improved in view of but not limited to the above-mentioned many factors. Summary of the Invention

[0004] To this end, the present disclosure provides a piezoelectric embedded overhead bin. The present disclosure performs overhead bin detection based on piezoelectric sensing technology, and a plurality of piezoelectric sheets are embedded in the sandwich layer of the overhead bin (e.g., during the manufacturing stage of the overhead bin). After manufacturing, it will not affect the overall shape of the overhead bin in appearance. And because the piezoelectric sheets themselves are small in volume, they will not have an obvious impact on the overall force of the overhead bin. This avoids the use of sensors such as cameras and infrared (these devices all need to occupy the space of the overhead bin or its surrounding area), and at the same time protects the privacy of passengers (taking cameras as an example, each camera is relatively large in volume. After installing cameras on each overhead bin, passengers will feel that their privacy is affected, and it also affects the cabin shape and space). In addition, the technical solution of the present disclosure can also observe the unoccupied luggage compartments according to the notified overhead bin occupancy, so as to recommend suitable storage positions to passengers according to their luggage, thus avoiding the service burden of checking overhead bins one by one and improving the boarding efficiency and the working efficiency of the crew.

[0005] According to a first aspect of the present disclosure, there is provided an overhead bin including one or more luggage compartments, wherein each luggage compartment includes: a piezoelectric sheet disposed in a load-bearing surface of the luggage compartment; a display screen disposed outside the luggage compartment, the display screen being capable of displaying the space occupancy of the luggage compartment; and a data acquisition device connected to the piezoelectric sheet, the data acquisition device being capable of acquiring an electrical signal from the piezoelectric sheet and transmitting it to a data processing device.

[0006] According to an embodiment, the data acquisition device is disposed on a non-load-bearing surface of the luggage compartment.

[0007] According to another embodiment, the luggage rack is a luggage rack of an aircraft, and the piezoelectric sheets are arranged at intervals in the load-bearing surface in the nose-to-tail direction of the aircraft, wherein the interval is less than or equal to the minimum dimension among the three-dimensional dimensions of a standard luggage case.

[0008] According to yet another embodiment, the piezoelectric sheets are arranged at the four corners and the central position of the load-bearing surface of the luggage compartment.

[0009] According to yet another embodiment, the data processing device is configured to: calculate the space occupancy of each luggage compartment based on the electrical signal; and transmit the calculated space occupancy of each luggage compartment to the display screen for display.

[0010] According to yet another embodiment, the piezoelectric sheets are embedded in the interlayer of the load-bearing surface during the manufacturing process of the luggage rack.

[0012] According to one embodiment, calculating the space occupancy of a luggage compartment based on the electrical signal includes: determining the pressure received by the piezoelectric sheets in the luggage compartment based on the electrical signal; determining the number of piezoelectric sheets with the pressure greater than a predetermined threshold; and determining the space occupancy of the luggage compartment based on the number of piezoelectric sheets with the pressure greater than the predetermined threshold.

[0013] According to yet another embodiment, the space occupancy of the luggage compartment is calculated as follows:

[0014]

[0015] where V 已占用 represents the occupied space of the luggage compartment; V0 represents the total space of the luggage compartment; m represents the number of piezoelectric sheets with the pressure greater than the predetermined threshold; and n represents the total number of piezoelectric sheets in the luggage compartment.

[0016] According to yet another embodiment, the occupied space and the unoccupied space of the luggage compartment are displayed in different formats on the display screen and / or the flight attendant control panel, where the display position of the occupied space of the luggage compartment on the display screen and / or the flight attendant control panel corresponds to the position of the piezoelectric sheets with the pressure greater than the predetermined threshold in the luggage compartment.

[0017] According to another embodiment, the method further includes: receiving a selection input from the flight attendant control panel for the unoccupied space of a specific luggage compartment; and causing a display screen associated with the specific luggage compartment to blink.

[0018] According to another embodiment, the method further includes: determining that the unoccupied space of the specific luggage compartment is currently occupied; and causing the display screen associated with the specific luggage compartment to stop blinking.

[0019] According to a third aspect of the present disclosure, there is provided a luggage storage system, including: a luggage rack according to the first aspect of the present disclosure, and a processing device configured to execute the method according to the second aspect of the present disclosure.

[0020] According to a fourth aspect of the present disclosure, there is provided an aircraft including the luggage rack according to the first aspect of the present disclosure.

[0031] The following detailed description presented in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein can be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details.

[0032] As described above, in existing aircraft, passengers need to select their own luggage storage locations during the boarding phase, thus blocking the passageways and prolonging the boarding time.

[0033] The present disclosure proposes a luggage rack, particularly a piezoelectric embedded luggage rack. This avoids the use of sensors such as cameras and infrared (these devices all occupy the space of the luggage rack or its surroundings), and also protects the privacy of passengers (taking cameras as an example, each camera has a relatively large volume. After installing cameras on each luggage rack, passengers will feel that their privacy is affected, and it also affects the cabin styling and space).

[0034] The present disclosure performs luggage rack detection based on piezoelectric sensing technology, and embeds multiple piezoelectric sheets in the luggage rack sandwich (for example, during the luggage rack manufacturing stage). Those skilled in the art know that piezoelectric technology is a mature technology, which means that when a piezoelectric sheet is subjected to pressure, the piezoelectric sheet can convert the pressure into current; when the piezoelectric sheet receives current stimulation, it can convert electrical energy into mechanical vibration of the piezoelectric sheet, thus realizing the conversion between electrical energy and mechanical energy. After manufacturing, it will not affect the overall styling of the luggage rack in appearance. And because the piezoelectric sheet itself has a small volume, it will not have an obvious impact on the overall force of the luggage rack. In addition, the technical solution of the present disclosure can also recommend suitable storage locations to passengers according to the luggage, thus avoiding the service burden of checking the luggage racks one by one and improving the boarding efficiency and the working efficiency of the crew.

[0035] Those skilled in the art will understand that a luggage rack (e.g., a luggage rack on an aircraft such as a civil aviation aircraft) may include one or more luggage compartments for storing luggage, and each luggage compartment may include an openable compartment cover plate and a load-bearing surface, which will not be elaborated here.

[0036] Reference is made below to Figure 1 , which shows a schematic diagram of a part 100 of a luggage rack according to an embodiment of the present disclosure. It can be seen that Figure 1 two luggage compartments included in the luggage rack are shown, one on the left is open and the one on the right is closed.

[0037] As shown in the figure, the luggage compartment may include a data acquisition device 101, a piezoelectric sheet 103, and a display screen 105. In Figure 1 the embodiment shown, the piezoelectric sheet 103 may be disposed in the load-bearing surface of the luggage compartment. In a preferred embodiment, the piezoelectric sheet 103 is embedded in the interlayer of the load-bearing surface during the manufacturing process of the luggage rack, so that it is not visible from the outside.

[0038] Continuing to refer to Figure 1 , the display screen 105 may be disposed outside the luggage compartment, for example, on the outside of the cover plate of the luggage compartment, for easy viewing. In one embodiment, the display screen 105 can be used to display the space occupancy of the luggage compartment.

[0039] According to an embodiment of the present disclosure, the data acquisition device 101 may be connected to the piezoelectric sheet 103 to collect an electrical signal from the piezoelectric sheet 103 and transmit it to a data processing device ( Figure 1 not shown in the figure).

[0040] In an embodiment of the present disclosure, the data processing device may be a flight control computer of the aircraft, and it may calculate the space occupancy of each luggage compartment based on the received electrical signal; and transmit the calculated space occupancy of each luggage compartment to the display screen 105 for display.

[0041] In a preferred embodiment of the present disclosure, the data acquisition device 101 may be disposed on the non-load-bearing surface of the luggage compartment. For example, as Figure 1 shown, the data acquisition device 101 is disposed on the fuselage side of the luggage compartment. In this way, damage to the data acquisition device 101 caused by the storage and pressure of luggage can be prevented. Of course, it can be understood that the data acquisition device 101 can also be disposed on the partition between each luggage compartment or at the corner of the load-bearing surface of the luggage compartment (where there is generally no pressure), which will not be elaborated here.

[0042] In another embodiment of the present disclosure, the luggage rack may be a luggage rack of an aircraft, and the piezoelectric sheets 103 are arranged at certain intervals in the load-bearing surface of the luggage compartment included in the luggage rack in the nose-to-tail direction of the aircraft. In a preferred embodiment, this interval can be determined according to the smallest dimension among the three-dimensional dimensions of a standard luggage (for example, less than or equal to the smallest dimension among the three-dimensional dimensions of the standard luggage), so as to ensure that each luggage can occupy at least one piezoelectric sheet 103 when being stored. In this embodiment, the standard luggage is in a substantially cuboid shape with dimensions in three dimensions (for example, referred to as length, width, and height). In a further preferred embodiment, considering that the luggage is generally placed flat on the luggage rack, such that the largest dimension (for example, the length dimension) of the luggage extends in the nose-to-tail direction of the aircraft, the above interval can be set to be less than or equal to the length of the luggage. In yet another preferred embodiment, in order to improve the accuracy of space detection, the above interval can be set to be less than the smallest three-dimensional dimension of the standard luggage, such as 1 / 2, 1 / 3, etc., so that the luggage can occupy more piezoelectric sheets when being stored.

[0043] In a preferred embodiment of the present disclosure, the piezoelectric sheets may be arranged in a side-by-side layout in the load-bearing surface, as shown in FIG. 2. Figure 2 The piezoelectric sheet 203 arranged side by side on the center line of the load-bearing surface is shown. In this way, the interval between the piezoelectric sheets can be set according to the width of the luggage, and the sensed pressure difference can be increased, so as to effectively judge the force area, and thus an appropriate number of piezoelectric sheets can be arranged according to the size of the luggage.

[0044] In another preferred embodiment of the present disclosure, the piezoelectric sheets may be arranged in a cross layout in the load-bearing surface. For example, the piezoelectric sheets may be arranged at the four corners and the center position of the load-bearing surface of the luggage compartment, as Figure 3 shown. Figure 3 A schematic diagram of the piezoelectric sheet 303 arranged crosswise on the load-bearing surface is shown. In this way, the piezoelectric sheets can be embedded at the four corners and the center position of the load-bearing surface, so as to form a plurality of triangular regions (the piezoelectric sheet 303 can act as the vertex of the triangular region). Thus, the triangular region where the potential change of gravity conduction is more significant is the occupied region, so that the space detection is more accurate.

[0045] It will be understood that Figure 1 the data acquisition device 101 and the piezoelectric sheet 103 shown in

[0046] It will also be understood that there may be one display screen 105 for each luggage compartment, or several luggage compartments may share one display screen 105, as long as passengers can conveniently determine which luggage compartments are occupied and which are vacant through the display screen 105, and details will not be elaborated herein.

[0047] Figure 4 FIG. 4 shows a flowchart of an example method 400 for luggage compartment space occupancy according to an embodiment of the present disclosure.

[0048] As shown, method 400 may include receiving an electrical signal from a data acquisition device at block 410. For example, in combination Figure 1 , the electrical signal may be acquired by data acquisition device 101 from piezoelectric sheet 103 disposed in the load-bearing surface of the luggage compartment. In an embodiment of the present disclosure, the flight control computer of the aircraft may receive the electrical signal acquired by data acquisition device 101 from piezoelectric sheet 103 disposed in the load-bearing surface of the luggage compartment.

[0049] Next, at block 420, method 400 may calculate the space occupancy of the luggage compartment based on the received electrical signal.

[0050] In a preferred embodiment of the present disclosure, calculating the space occupancy of the luggage compartment based on the electrical signal may include: determining the pressure exerted on the piezoelectric sheet in the luggage compartment based on the electrical signal; determining the number of piezoelectric sheets with the pressure greater than a predetermined threshold; and determining the space occupancy of the luggage compartment based on the number of piezoelectric sheets with the pressure greater than the predetermined threshold. Further according to this embodiment, the space occupancy of the luggage compartment is calculated using the following formula:

[0051] where V 已占用 represents the occupied space of the luggage compartment; V0 represents the total space of the luggage compartment; m represents the number of piezoelectric sheets with the pressure greater than the predetermined threshold; and n represents the total number of piezoelectric sheets in the luggage compartment.

[0052] Finally, at block 430, method 400 may include transmitting the calculated space occupancy of the luggage compartment to the flight attendant control panel and / or a display screen disposed outside the luggage compartment for display. For example, the current usage status of the overhead bin may be shown on the screen.

[0053] In an embodiment of the present disclosure, the overhead bin display screen presents the "available space" in a visual form on the display, showing the current usage status of the overhead bin. On the other hand, the flight attendant control panel (CMT) receives data on the usage status of all overhead bins on the aircraft, and the flight attendant can operate the CMT to view the usage status of the entire aircraft. Thus, when passengers board the aircraft, the flight attendant can recommend available luggage compartments to passengers based on the passengers' seats and luggage.

[0054] In one embodiment of the present disclosure, the occupied and unoccupied spaces of a luggage compartment can be displayed in different formats on a display screen and / or a flight attendant control panel. For example, occupied space can be displayed in red, while unoccupied space can be displayed in green. Further according to this embodiment, the location where the occupied space of the luggage compartment is displayed on the display screen and / or the flight attendant control panel corresponds to the location of a piezoelectric patch in the luggage compartment that is subjected to a pressure greater than a predetermined threshold. In one example, flight attendants can use the space occupancy displayed on the flight attendant control panel to inform passengers of which luggage compartment to store their luggage upon boarding. The space occupancy information on the luggage compartment display screen can help passengers shorten the time it takes to select the appropriate luggage compartment, thereby speeding up boarding efficiency.

[0055] In a preferred embodiment of the present disclosure, method 400 may further optionally include receiving a selection input from a flight attendant control panel for an unoccupied space in a specific luggage compartment, and flashing a display screen associated with the specific luggage compartment. For example, when a passenger is boarding an aircraft, a flight attendant may recommend a specific luggage compartment to the passenger and make a selection input on the flight attendant control panel (e.g., click on the specific luggage compartment). In this case, the display screen associated with the selected specific luggage compartment may flash to direct the passenger to the compartment.

[0056] In further accordance with this embodiment, upon determining that the unoccupied space of a particular luggage compartment is currently occupied (eg, a passenger has stored luggage therein), method 400 may include causing a display screen associated with the particular luggage compartment to stop flashing.

[0057] In one embodiment of the present disclosure, the display screen may employ liquid crystal displays (LCDs) of various sizes, such as a local LCD display in the luggage compartment, a larger central LCD display in a specific area, a movable LCD display, and the like.

[0058] Thus, the present disclosure provides a novel luggage rack that utilizes an embedded aircraft luggage rack piezoelectric chip arrangement. Multiple piezoelectric chips are embedded within the interlayer of the luggage rack to detect luggage placement, thereby minimizing the space occupied by the luggage rack and protecting passenger privacy. Furthermore, the occupancy status of the luggage rack is graphically displayed on the flight attendant control panel, allowing flight attendants to view the overall aircraft luggage rack usage status and recommend available storage locations to passengers.

[0059] Figure 5 A schematic diagram of a luggage storage system 500 according to an embodiment of the present disclosure is shown. As shown in the figure, the system 500 may include a luggage rack 501 (e.g., according to Figures 1-3the described luggage rack) and a processing device 503 (e.g., the flight control computer of an aircraft), where the processing device 503 is configured to execute according to Figure 4 the described method 400.

[0060] Figure 6 FIG. shows a schematic diagram of an exemplary aircraft 600 according to an embodiment of the present disclosure. According to one embodiment, the aircraft 600 may include according to Figures 1-3 the described luggage rack. Further according to this embodiment, the aircraft 600 may further include a flight control computer, and the flight control computer may be configured to execute according to Figure 4 the described method 400.
